Dynamic AF Mode with Closest Subject Priority is activated) appears when
Dynamic AF is selected in the LCD panel.
[ ]: Single Area AF R
Vyith Single Area AF, only the focus brackets selected among five focus
areas is used for autofocus. This mode is useful for achieving accurate
focus on a selected focus brackets when shooting a stationary subject.
[+]: Dynamic AF E^/ITFI (in Dynamic AF Mode with Closest Subject Priority)
In Dynamic AF, you designate the primary sensor (the first to detect the
subject), then if the detected subject moves. Dynamic AF automaticaily
shifts to the next sensor that detects the subject, then the next again,
shifting among the progression of sensors as the subject moves. Dynamic
AF thereby follows and maintains accurate focus even on subjects that
move irregularly. (LCD panel and viewfinder indications do not change as
sensoring shifts in Dynamic AF mode.) Dynamic AF Mode with Closest
Subject Priority can also be activated in Dynamic AF mode. See next
page.
If the focus mode is set to Single Servo AF in Dynamic AF, the camera is
automatically set to Dynamic AF Mode with Closest Subject Priority in initial
setting.
